really bizarre game. not sure if thats good or bad reminds me a lot of beneath a steel sky for some reason.


I love the ambiguity in the story.  It's the type of story that you're left thinking about and whether or not you made the right choice.  The art, music, and voice acting was fantastic.  Even in the middle of summer, I felt colder after the experience.


Amazed by how much story you could tell within one-screen game. Puzzles were fun and I liked how you were not ashamed to put the fade in - fade out screen when the character needed to climb on that barrel. Such an old school feel. I will play your other adventures as well :) 

The Game was good,but i want to know if i made the rite decision in the end. loved it.


The voice acting really make the game more tense, ITs so much fun and at the end i still confused 

Nice game with great voice acting! Loved it!!

Hey Powerhoof, I really like your game concept, will you be bringing Peridium to Mobile Platforms in the Future?

Tres bonne surorise

J aime beaucoup avec la voix du narrateur ca change tout c est excellent  !

your game was fascinating thank you so much i really loved it :):):):)


I rly don`t knw how this got into my device but really thx for unconscious me for this gift wht a wonderful voice acting dudeeeeeeeeeeeee !!!!!!!!!

He he, thanks. Friend of ours (@YeOldShrimpEyes) does the VO for all our adventure games :D


Very good work and it's amazing you did all that in just five days! Great voice acting and I enjoed the atmophere and the graphics.


Impressive game, very evocative of the paranoia in The Thing and Who Goes There/Frozen Hell, the original stories that inspired John Carpenter's movie. Would love to see this expanded into a longer game!


An incredible game, I've really enjoyed it. I recently both featured it as my first game on my Short Games and Demos corner of my Youtube channel, as well as my first story on Medium. Check it out: 

A fantastic Point & Click adventure. I cannot believe this was made in 5 days. This recently appeared on my Game Review series First Take: 

Fantastic game! You really set up a high bar of what is achievable in 5 days :) Excellent work!!

Really cool game, I liked it a lot!

-Made a Video. (Old Video)


Brilliant work! Can't wait for The Drifter.


Oh, sick! Especially that moment when you first walk across the room and see... how far things have gone. Very nice, very creepy, great art! The full voice acting is something special, as well.

Super enjoyed this game!  We played Alluvium before and loved it; was definitely not disappointed by this game :D


great game, quick and terrifying.

Completely brilliant.  I suspected where it was heading, but the buildup was perfect.  



Omg, so many questions !!!! Keep up the good work, I'd die for a long game of yours tbh. There's something about your games that make them familiar but original, idk, really great. Thanks for making them.

for some reason the mouse is not working in the linux version

Same problem here - it would be amazing if this could be fixed, as the game's intro was so extremely promising!

Oh, damn. Is there any particular distro or whatever you're using? No promises, but I can try and take a look.

(1 edit)

Doesn't seem so - it neither works on Slackware64-current nor on openSUSE Leap 15.0, but I'll try with a Ubuntu Live CD tomorrow to be sure.

The problem is that the mouse cursor can't be moved - clicking seems to work fine, though, but that's obviously not enough to play an adventure game ;-) The log file doesn't seem to contain any relevant information about the problem.

This problem does not occur with Murdercide 2017 and Alluvium, though Blood Mechs also seems to be affected. Your other games which I've played already don't seem to support mouse input.

Oh very weird that murdercide/alluvium work and peridium doesn't. Hrmm. Could be the specific version of unity I used for that one, I know there were issues with one version with controllers being plugged in or something. I've rebuilt with a later version, so try it again (v1.4) and let me know if that works!


Yes, that did it - thanks a lot, I've just finished the game twice!

It has it all: It's a bit frightening, it's a bit funny, but it's such a polished 2D adventure experience! The dialogues are well written, the puzzle design is satisfying and the voice acting is, as usually, top-notch. I felt in love with "Peridium",  so I was very happy to see that you not just got the 1st place in the whole Adventure Jam 2017, but also the Developer's Choice Award as well as two Judges' Picks. And I have to agree with them, that's why I not just wrote a praising article about it and uploaded a playthrough video, but I also included it in our GOTY 2017 list. Well deserved, because you guys showed off all your skills once again. Thank you for this game. <3

Best wishes,

Thanks Sebastian!  I'm hoping to do something for the upcoming Adventure Jam too!

I'm super glad to hear that! Can't wait to see what all the marvelous devs may come up with in that one... <3 And I'm definitely looking forward to your new entry! :)

This is one of the creepiest 2D games I've ever played. Good job, man!

This pixelated HORROR game is freaking amazing like  for real!
 It was a pleasure to make a video of this game!
So much feels in this one...

Share and Like if you enjoyed!

Great voice acting make this game worth playing.  Also very cool endings. Great Job... :) 

I liked this game a lot, the ending had me like "WTF" but it was good nonetheless!

Hey nice game! I really enjoyed playing it! Here is My let's play of the game! :D

This game is awesome, I'm glad I got to experience it. It sucked me in from the start, I love the pixelated art style it has, and the voice acting is absolutely phenomenal!

The game blew my expectations out of the water. It's creepy, dark and clever. I'd recommend anyone and everyone to try this game out.

Also, if you don't mind, I recorded a short let's play of the game.

Cheers and best wishes, I hope to see more from you in the future!

wow this is absolutely brilliant!  right when the (amazing) voice acting started i immediately knew i was playing something professionally made! i wish more games had the format of this one, that allowed me time to think and dramatically increased the tension without any major jumpscares (VERY MUCH APPRECIATED) despite a lot of scenes taking me off guard.  solid disturbing imagery, but i only once found myself covering my eyes (so i could still play!) AND no tutorial needed while still feeling scared! 10/10

One of the most awesome - short experiences i've ever had!I really liked the voice acting and the whole concept was mind intriguing!Followed you for upcoming projects or the final release of this one  xD
Here is my Let's Play: 

WONDERFUL GAME!!! it reminded me of The Thing by John Carpenter (my fav horror movie), AWESOME JOB dear devs!!! GREAT GAME :D P.s i did a video of it :P
